经编针织物双向拉伸性能研究

测试了5种经编针织物的双向拉伸性能,考察了拉伸方向、拉伸速率及织物结构对拉伸性能的影响。当织物结构相同且一个方向固定、另一个方向拉伸时,横向拉伸的断裂强力与断裂伸长大于纵向拉伸的。随着拉伸速率提高,织物的断裂强力与断裂伸长先增大后减小。当织物组织结构与参数相近时,双向拉伸的各项指标相差不大。单梳经绒织物的断裂伸长比经绒平、经平绒、菱形及四角网孔4种双梳织物的大。

Study of the bi-directional tensile properties of warp knitted fabrics

This paper tests the bi-directional tensile properties of five warp knitted fabrics and studies the influences of stretching direction,stretching speed and fabric structures.Under the condition of same fabric structure,when one direction is clamped and the other direction is stretched,the breaking strength and elongation in the course way is larger than those in the wale way.With the increase of stretching speed,the breaking strength and elongation first goes up and then goes down.When the fabric structure ...
